If this is jumping on the bandwagon of ABBA's spectacular return then I hope every artist is going to do it (except for a return of Mama Mia the musical/movie).
Incidentally, and this has absolutely nothing to do with MSP's music, today I learned about the phenomenon "mockbuster", movies created for no other purpose than to ride on the coattails of a contemporary blockbuster or the promotion thereof. It appears to be connected with the mysterious The Asylum production company.
Of course I've always known these kind of movies - usually by accidentally picking the wrong version - but I didn't know that it was a "thing" and that there was something very organised about it.
